  • Analysis of the equations governing the motion of a degrading elastic solid due to diffusion of a fluid 

    Quintanilla de Latorre, Ramón; Rajagopal, Kumbakonam (2014-10)
    Article
    Open Access
    Degradation of solids bearing load due to the infusion of moisture when exposed to the environment can leads to a decrease in their load carrying capacity and can also lead to the failure of the body from performing its ...
  • Computable bounds of functional outputs in linear visco-elastodynamics 

    Verdugo Rojano, Francesc; Díez, Pedro (2012)
    Article
    Open Access
    This work presents a new technique yielding computable bounds of quantities of interest in the framework of linear visco-elastodynamics. A novel expression for the error representation is introduced, alternative to the ...

  • Decay of solutions for a mixture of thermoelastic solids with different temperatures 

    Muñoz Rivera, Jaime E.; Naso, Maria Grazia; Quintanilla de Latorre, Ramón (2016-02-06)
    Article
    Open Access
    We study a system modeling thermomechanical deformations for mixtures of thermoelastic solids with two different temperatures, that is, when each component of the mixture has its own temperature. In particular, we investigate ...
  • Experimental study on inter-particle acoustic forces 

    Garcia Sabaté, Anna; González Cinca, Ricardo; Hoyos, Mauricio; Castro, Angelica (Acoustical Society of America, 2014-03)
    Article
    Restricted access - publisher's policy
    A method for the experimental measurement of inter-particle forces (secondary Bjerknes force) generated by the action of an acoustic field in a resonator micro-channel is presented. The acoustic radiation force created by ...
  • Inverse mechanical analysis for biological tissues 

    Lauwaert Luyten, Felix (Universitat Politècnica de Catalunya, 2016-10)
    Master thesis
    Open Access
    This study focuses on the application of inverse finite element methods and computational mechanic techniques in order to simulate the spinal cord s contraction described in the previous section. Specifically, the aim is ...
  • Modelling hydrogels with Onsager’s variational principle 

    Collivadino, Andrea (Universitat Politècnica de Catalunya, 2017-07)
    Master thesis
    Open Access
    The goal of this Master's thesis is to provide a physical and mathematical model that attempts to describe the deformation process of hydrogels. Hydrogels are commonly defined as three dimensional networks of hydrophilic ...
  • Modelling of non-linear viscoelastic tissues with bar elements 

    Asadipour, Nina (Universitat Politècnica de Catalunya, 2012-03)
    Master thesis
    Open Access
    In this work we develop a viscoelastic bar element that can handle multiple rheological laws with non-linear elastic and non-linear viscous material models. The bar element is built by joining in series an elastic and ...

  • Models computacionals de fractura fràgil 

    Pons Puntí, Adrià (Universitat Politècnica de Catalunya, 2019-01)
    Bachelor thesis
    Open Access
    L estudi de la propagació de fractures en diferents materials és un camp en augment en els últims anys. Ja sigui per tal d estudiar el comportament d alguns materials davant de diferents esforços o per preveure com ...
  • Obtaining gravitational models from planetary ephemeris 

    Sánchez Martín, Patricia (Universitat Politècnica de Catalunya, 2012-03)
    Master thesis
    Open Access
    Ephemerides describe the position and velocity of a celestial object as a function of time. The ephemerides data are obtained by solving the fundamental equations of motion of the body, which is obtained by applying the ...
  • On the decay of solutions in nonsimple elastic solids with memory 

    Pata, Vittorino; Quintanilla de Latorre, Ramón (Elsevier, 2010-02)
    Article
    Restricted access - publisher's policy
    The decay of solutions in nonsimple elasticity with memory is addressed, analyzing how the decay rate is influenced by the different dissipation mechanisms appearing in the equations. In particular, a first order dissipation ...
  • Pushing SEA beyond its limits: a model for real building structures 

    Díaz Cereceda, Cristina; Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (2013)
    Conference report
    Open Access
    The main challenge for models of building acoustics is being able to consider all the geometrical and physical details of real structures with a reasonable computational cost for high frequencies. The SEA (Statistical ...
  • Uniqueness in thermoelasticity of porous media with microtemperatures 

    Quintanilla de Latorre, Ramón (2009-09)
    Article
    Restricted access - publisher's policy
    The problem determined by thermoelastic deformations when the internal energy is not positive definite, becomes ill-posed. We call that this kind of situation happens in the study of prestressed thermoelastic solids. Thus, ...
